Finetune radio not finishing songs

I'm trying to listen to finetune on the wii Internet channel (obviously), but it will only play part of a song-- a few seconds or almost to the end and skip on to the next one. It was playing full songs with no problem until I searched for a new artist tag. I clicked on the right artist but it pulled up an unrelated radio. Tried again and it did the same. Tried again and it pulled up a different unrelated station. After that I entered another artist tag and got the right station but then it started randomly cutting all the songs off. It's infuriating. Hellllp!!!
